Amplifier power needed by 1.7s

Thats a large room, how loud doyou want to play your music?

Going bridged mono opperation will give you some benifits. Please do not under value acoustical room treatments. That can make a bigger change and improvement in sound quality than simply changing components. I have had 1.7's and they can give you the "you are there" experience if properly integrated into your room. Definately try moving your 1,7's and your listening position (key). Also, try tilting them forward a bit, this made a noticeable improvement in my room with my 20.1's. I also have had a leap forward in my sound quality replacing the stock Mcintosh tubes in my 2301's and c500t preamp with Gold lion tubes. Hope this gives you some ideas....enjoy your Maggies!

Wyred4sound works well on the 1.7s and the price is right for the amount of power (1000 watts @ 4 ohms). The Maggies love all of that power and you won't need the sub.

I think your room size (20x30) stretches the intended volume for 1.7s. The Cronus Magnum IS a great fit for this speaker. The Absolute Sound used that amp to review the Maggie 1.7 and came away all aglow. I told my audiobuddy (who owns 1.7s) about the Rogue Cronus Magnum, he bought one and absolutely loves the pairing.

Since you are listening at 11', the Cronus Magnum may be enough, but you may want to add some subs to flesh out that 4800 cu. ft. space. My audio buddy matched these SVS subs to his 1.7s and likes the combo very much.

Thanks to all for your thoughtful (and helpful) suggestions. I do not listen to much rock nor do I like ear splitting levels. Prefer acoustic vocal, jazz and orchestral music played at reasonable levels. In the past I have used very high output SS and 'stats. I found it very revealing but somehow fatiguing when listened to for an extended time. I find that source material becomes much more of an issue as such a setup is brutally revealing. There just seems to be something about tubes. There's so much poorly recorded material out there. Source is a modified (R.A.M.) Oppo CDP direct into amp(s).

I have the Maggie 1.7s with an Audio Research DSI-200 and two REL subs...a good recording will not sound edgy or brittle with this combination...tubes only smoothed out the crap recordings while losing some detail in the excellent ones.
